Homework Help: Maths

Posted by Karla on Monday, August 29, 2011 at 5:37am.

Hey :)
I was wondering if someone could tell me if this answer and working is correct or not...

Cos theta =-0.25
Cos inverse -0.25 = -14
therefore theta equals:
180--14=194or/and
180+-14=166

Any help would be much appreciated :)
Thanks!
